Santolina chamaecyparissus
Lavender Cotton is a small, aromatic evergreen shrub characterized by its silvery-gray, finely divided foliage. It typically grows to a height of 1-2 feet. It is primarily grown outdoors as a ground cover, edging plant, or in rock gardens for its unique texture and aromatic properties. While it can be grown indoors, it requires very bright light and well-draining soil to thrive, making it challenging for most indoor environments. Its button-like yellow flowers appear in summer, adding further interest.

❓ Frequently Asked Questions — Comparing These Plants
Lavender Cotton
What are the light requirements for Lavender Cotton?
Lavender Cotton thrives in full sun, requiring at least 6 to 8 hours of direct sunlight per day. Insufficient light can lead to leggy growth and reduced flowering. When grown indoors, place it near a south-facing window where it can receive ample sunlight. If natural light is limited, supplement with grow lights to ensure optimal growth and flowering. Rotating the plant regularly will ensure even light exposure and prevent it from leaning towards the light source. Providing adequate light is crucial for maintaining the plant’s compact shape and vibrant foliage color.
How do I care for Lavender Cotton?
Lavender Cotton requires full sun and well-draining soil to thrive. Water sparingly, allowing the soil to dry out completely between waterings, especially during the winter months. Fertilize lightly in the spring with a balanced fertilizer to promote healthy growth and flowering. Prune regularly to maintain its shape and encourage bushier growth. Avoid overwatering, as this can lead to root rot. Protect from excessive winter moisture in colder climates. Lavender Cotton is relatively pest-free, but monitor for aphids and spider mites. Provide good air circulation to prevent fungal diseases. Deadhead spent flowers to encourage continued blooming.
How do I propagate Lavender Cotton?
Lavender Cotton can be propagated easily through stem cuttings. Take 4-6 inch cuttings from healthy stems in the spring or summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in well-draining soil and keep them moist but not waterlogged. Place them in a bright location with indirect sunlight. Rooting typically occurs within a few weeks. Division is also possible, carefully separating the root ball of a mature plant and replanting the sections. Keiki formation is not typical for Lavender Cotton.
